LACE FABRIC.

Application filed February 18, 1914.

To all whom it may concern Be it known that I, EDWIN S. RoBnnTs, a citizen of the United States, and a resident of Gouverneur, in the county of St. Lawrence and State of New York, have invented certain new and useful Improvements in Lace Fabric, of which the following is a specification.

My invention relates to lace fabric, such as may be made on a lace curtain machine.

The object of my invention is to so con struct the fabric that it will be substantial and durable and so that it will be of novel appearance.

Another object is to produce a lace fabric of this character which will be no more expensive to make than other fabrics of a corresponding grade; and to produce a fabric which may be made upon machines which are now in general use for making lace curtains.

Under my present invention lace fabrics may be made having solid or filled portions of rectangular shape and with openings of rectangular shape, all arranged to produce a very pleasing eifect; and the fabric may be of substantial construction. Fabrics may be made according to my invention, suitable for lace curtains, or they may be made of heavier threads and be suitable for draperies, portieres and such like.

The principle of my invention resides in making a lace fabric having the warp threads spaced different distances apart and in having some of the spool threads arranged as usual and others combined in such manner that they follow along together in the design and are tied to the same warps.

In the drawings forming part of this application, Figure 1 is an elevation of a portion of lace fabric constructed in accordance with my invention, as it ordinarily appears to the observer. Fig. 2 is a similar view of one side of the fabric, made on an enlarged scale to show the construction, Fig. 3 is a similar view of the reverse side of the fabric, and Fig. 4 is an enlarged detail showing the fabric as viewed from. the same side as in Fig. 3.

The ground work or foundation of the fabric consists, as in other lace fabrics, of the warp threads, though these are here arranged in a novel way. These warp threads maybe said to be of different gages or to-be arranged at different distances apart. Sev-' Specification of Letters Patent.

eral of these warp threads are arranged the same, or substantially the same, distance apart, while others are arranged different or greater distances apart. There may be what might be called a series of groups of warp threads, each group being spaced a greater distance from the adjacent groups than the distance be tween the individual warps of a group. In constructing the lace for instance on a six point machine, the warps may be threaded through the warp bar in this manner; three warps threaded through their respective apertures in the bar and the next warp omitted, then three threaded and one omitted, etc. \Vhere a warp is omitted there will naturally be formed a wider space between the adjacent warps. This is stated merely as an example, as the particular numbers and arrangement may be more or less varied without departing from the structural character of the fabric. If the usual lace curtain machine is employed in making the fabric, a certain number of the warps may be omitted in the above manner, and the corresponding bobbins and carriages removed.

In the drawings I have shown the warp threads running vertically. The warp threads 1, 2 and 3 for instance, are shown spaced equally apart, or of the same gage. In the next position the warp is omitted; and then the threads 1, 2, 3 are repeated; so that the distances between the threads 1, 2, and 2, 3, are alike, but the distance between the threads 3, 1, is greater than the distance between any two of the threads 1, 2, or 2, 3.

For each warp thread there is a bobbin thread for tying the spool threads to the warps; and, since the warps are arranged different distances apart, so the bobbin threads will be arranged to correspond. The bobbin threads 4, 5, 6, are arranged to tie on the warps 1, 2, 3, respectively, and they are, therefore, approximately the same distance from each other; but the distance between 6 and 4 is greater than the distance between 4 and 5, or 5 and 6. In order to obtain this arrangement I prefer to omit a certain number of bobbins and carriages by removing them from the machine. For instance, in the making of the fabric here illustrated I arrange the three bobbins carrying the threads 4, 5, 6, in the usual manner, these corresponding with the warps 1, 2, 3. The next or fourth bobbin is omitted or removed from the machine; and this arrangement is repeated throughout the machine.

Th 1 1 hre ds a tai d t the full number. That is, there are as many spool threads as there ordinarily would be in customary practice, but they are differently arranged. If for instance, the warps are arranged three in an'd'oneout, thisPomissio'n is not followed as to the spool threads, but there will be as many of these as the ordi nary gage of the work calls for. That is, if the warps 1,2,3, are arranged to correspond with a sir; point arrangeiiie'nt" then there will befsay, siX's'pool threads'to the inch; but they will notbe equallyfspaced "in'the con struction. In the making" of the fabric here shown'l arrange three spool threads in'the usual manner, "threading. them through the usual aperturesin' the guides on the spool bar. In "tl'ie next positioh the spool thread is'not threaded in the usual manner, but it is carried over and threaded through the same guide asthe adjacent thread; l

Inthe fabric here' shown the warps 1, 2, 3, are "equally spaced and'the warps 3,1 are spaceda greater distance apart. The spool thread. 7 passesback and forth between the warps l and '3, crossing the intermediate warp2; and it is tied to the warps 1, 3, by thebobbin threads 1, 6', respectively. The spool thread 8' passes back and forth betw'een the warps '1 and 2 and is tied to them by the bobbin threads 5, respectively and this construction preferably'continues down the full length of the material, forming a sort of bar appearance. Thisarrangement is true ofall the' several spool threads and 8 throughout'the width of the fabric. The spool threads 9, follow together and they pass back and forth between the warps l, 3, and are tied to them the bobbinthreads 1-, h, respectively. The spool threads,- in'this arrangement, are double; or in multiple across the wider spaces formed between the more distantly spaced warps,'so that this space is filled sufiiciently to .producethe deslred appearance and st rength. This arrangement is continued down the fabric for the desired distance; and then a change occurs. At any point, say at l1,"the.spool threads 9, 10, still following togetheryare p llar-ed down the warp 1 andare tied by the bobbin thread 4:. At any lower point, say at 12, the previous construction is repeated; that is, the spool threads 9, 1O, are again carried back and forth between the warps 1, 3, and are tied by the bobbin-threads 4c, 6.

By means of the above construction it is posslble. to produce an article of; novelappearance and of substantial construction. Both the upright and cross bars of the-design are substantial and permanent. The fabric consists of rectangular filled portions inclosing' rectangular openings which will properly retain their shape. 1

Having described my invention, what I claim is: 1. A lace fabric comprising a plurality of warp threads, a plurality of bobbin threads a plurality of spool threads, said Warp threads beingarranged in diflerent gages, a plurality of said spool threads passing, together,back and forth between the warps of wider gage, thence pillareddown one of said warps'and again passing back and forth,to gether,'between said warps of wider gage, said spool threads being tied to the warps by said bobbin threads. x

2. Alace fabric comprising a group of warp threads, arranged in the same gage, another group of warp threads arranged in the same gage as the first group, the said groups being arranged in a gage of greater width than the gage of the individual warps of the groups, spool threads providing a filling between the warps of eachgroup and a ur l ty f po l h ad ol w n t gether, and passing back and forth between adjacent warps of the respective groups, and thence pillared down one of said warps and again passing back and forth between said adjacent warps, to form an interrupted filling, and bobbinthreadstying said spool threads to thewarp threadsa '3. A lace fabric comprising groups of warp threads haying the several groups arrangedin thesame gage, and'having the groups arranged in a relatively wider. gage than the individual warps 'of-the groups, a filling for the warps of each group, comprising spool threads looped back and forth, respectively between adjacent and remote warps-ofa group to form a continuous filling between said warps,-bobbin threads tying said spool threa'ds to said warps, and. a plurality of spool threads following together and looped across between adjacent warps of the different groups, and being thence pillared along one of said warps and again looped across between said adjacent warps of different groups, to form an inter rupted filling between different groups of warpsand bobbin threads tying the saidlast mentioned spool threads to'thexwa-rps.
